Distance learning is concerned with subjects like pedagogy and andragogy. These subjects require field trips. A lot of students, both from the nation and abroad apply for these courses. Thus it is not always possible for students to come over and attend field trips, especially the ones who live abroad and are pursuing the course online. For them the course is sent through the net; all the relevant details that are necessary for pursuing the course. This is called distant learning; where you need not be there, present at the place of study, yet you can acquire all the relevant details. This is a very efficient method that is employed by professionals throughout the world for a cost convenient program.
